MACHINE FOR THE MANUFACTURE OF NON-PASTED TUBES FOR CIGARETTES.

SPEGIFIGATION forming part of Letters Patent No. 514,589, dated February13, 1894.

Application filed September 27, 1890. Serial No. 866,298.

(No model.) Patented in England July 19, 1886, No. 9.368; in GermanyJuly 25, 1886,1lo. sarss; in Switzerland February 1, 1889, No. 386, andin France September 12, 1890. N

To all whom it may concern:

Be it known that I, ANATOLE EDOUARD Dn- COUFLE, of the city of Paris,Fran ce, have invented an Improved Machine for the Mannfacture ofNon-Pasted Tubes for Cigarettes, of which the following is aspecification, and for which I have obtained Letters Patents in thefollowing countries, to wit: Great Britain July 19, 1886, No. 9,368;Germany July 25, 1886, No. 38,766; Switzerland February 1, 1889, No.386, and France September 12, 1890, No. 208,197.

My invention relates firstly to mechanical devices for the continuousmanufacture of paper tubes, which are not pasted, and secondly to thegrouping and correlation of these various mechanical devices fromwhichthere results a machine which is, so far as I am aware, novel as to itsaction and arrangement, and a product remarkable both for its uniformity and quantity.

According to my invention the paper, arranged in the form of a bobbin orreel, is transformed into a closed tube by the internal interlocking ofthe longitudinal edges of the endless paper; then cutters divide thisclosed tube into definite lengths.

In the drawings hereto annexed, Figure l is a side elevation of myimproved tube machine. Fig. 2 is a plan view of the same. Fig. 3 is anend view of the machine with some of the parts removed. Fig. 4 is alongitudinal section of the tube forming mechanism. Fig. 5 is alongitudinal section of the spindle for forming the tubes. Fig. 6 is aplan of the same. Fig. '7 shows five detail views of the interlockingfolder. Fig. 8 is a view on line l-2 of Fig. 4. r Fig. 9 is acrosssection on line 3- of Fig. 4, showing also the tube in course offormation. Fig. 10 is a cross-section of the paper tube as shown in Fig.9. Fig-.11 is a cross-section on line 5-6 of Fig. 4, showing also thetube in course of formation. Fig. 12 is a cross-section of the papertube as shown in Fig 11. Fig. 13 is a cross-section on line 78 of Fig.l, showing also the tube in course of formation. Fig. 14 is a crosssection of the paper tube as shown in Fig. 13; and Fig. 15 shows acompleted tube cut to length. 7

A foot or stand a supports a cast-iron ta ble 0. on which are arrangedcomponent parts of the machine.

I) is ashaft arranged in bearings 19 b bolted to the upper side of thetable. This shaft carries a cam c' which operates the tube cutter. A camg is also mounted on the shaftb to feed forward the paper intermittentlywhen it is desired so to feed it. The shaft 1) is driven by theintermediate shaft 0 provided with the pulleys 0 0 the liy-wheel 0 and aspur-wheel b gearing direct with another spur-wheel Z2 on the shaft 1).The paper 19 rolled up on a bobbin or reel 13' mounted loosely on theaxis of a forked headstock p is led over a first roller 19 carried atthe end of a long flexible spring 19 which is fixed to a projecting part29 0f the frame. From the roller 19 the paper is led over the roller 19which 1mmediately precedes the formation of the tube. The bobbin or,reel 19', which is loose on its axis, is subjected to the action of abrake or pallet 13 rubbing at its free end against the metallic ringwhich forms the boss of the bobbin or reel. From the last guide-rollerpthe paper 13 passes through an opening in the support f of thecounterpart 7 of the stampj thence it is conducted into a shaper q(supported on the pillar Q),in which is suspended the end of acylindrical spindle r. The paper taking the cylindrical section has itsedges bent toward the connecting piece q of the spindle. This spindle ris adjusted ii the shaper g by a screw (1 tapped into a gap ofthe-shaper and bearing on a prolongation of the said spindle. Beyond theshaper q the paper incloses or surrounds the spindle '1', which, beingof cylindrical form on its under side, preserves the cylindrical sectionof the paper. On its upper side the spindle r is hollowed out into alongitudinal groove r into which are folded down the edges of the paperby means of a presser 3 having a special acting surface, as shown inFig. 11. The presser is suspended at the end of a spring 8' which issupported on the pillar Q. At the end of the groove r in the spindle thepaper surrounds the folding devicet let into the spindle, as shown inFigs. 4, 5 and 6. The folder or former t is a piece of strong, finegrained metal pierced with a conical way having a tolerably largeentrance and every small outlet. A slit t, Fig. 7, widened out and thenprogressively reduced in size, forms the opening of thisway at the upperface of the piece. The folded down edges of the paper follow the slit tand are rolled, folded, hooked or interlocked one in the other, as thepaper advances, by the decreasing sections of the folder or former 25.Just before the tube reaches this piece If it engages in a shaper u(Figs. 1, 2 and 4) loose on the spindle and concentric therewith, whichshaper prepares the fold for closing, and limits the diameter of thetube. A fingeru projects from '0 and takes behind the shaper, thuspreventing longitudinal displacement. Then at the outlet of the folderthe tube enters between the milled roller r (Figs. 4., 5, 6 and 8) letinto the spindle r, and the feed rollerv placed immediately over it. Themilled roller 0" and the feed roller i; exert upon the paper, which theydraw forward between them, a pressure, with or without creasing, whichcompletes the closing of the preceding fold by incorporating, one in theother, the various thickness of paper which have been brought togetherby the action of the folder 23. By these means thelongitudinal joint isobtained as shown in Fig. 15. The paper receives the required motion oftranslation either continuously or intermittently. When the motion iscontinuous the roller n has imparted to it a continuous rotary motion byany desired means; but when the motion is intermittent it is produced bymeans of a rack a: which is raised and lowered alternately by lever goperated by the/cam g, as shown in Fig. 3. This motion of the rack mtransforms into an intermittent rotary motion, in one direction of thefeed roller '0 by means of pinion a." and the wheel 164, both loose onthe shaft of u having thereon pawls to engaging a ratchet a fast on theshaft of v, or on any other suitably arranged pawl and ratchetmechanism. The feed roller '0 may be rotated sufficiently by a singlemovement to produce a feed of the paper equal to the length of thecigarette tube; or it may be rotated so as to correspond to the feedingforward of half a length, as may be arranged. In the latter case thefeeding forward of a complete length of tube is effected at twooperations. WVhen the paper tube leaves the closing devices o and o itis completely closed throughout its length, with the edges of the paperfolded or interlocked into one another and placed inside the tube. Itmay be thus produced in any lengths, and even in a single length equalto the total length of the paper on the bobbin or reel.

For cutting oif the tubes to length equal to that the cigarette isintended to have, there are placed near the closing devices r o andimmediately after the front end of the spindle T, which is formedpreferably as shown in Figs. 5 and 6, two branches 2" 2' jointedtogether at i see Fig. 3. are held normally closed by a spring 4 and areopened by the act-ion of a cam 2' which makes a half turn between thesaid branches. The movement of this cam 2' is efiected after each feedof a length of tube by means of the cam '11, the lever i, the connectingrod or link i and the lever i The front ends of the branches 1"? arefurnished with blades i which can be easily and quickly mounted anddismounted for sharpening or replacing. It will thus be seen that whenthe rear ends of the pivoted members are forced apart the blades on thefront end thereof will come together and sever the tube. The feedingroller v rests, by the ends of the axis on which it is fixed, in thebearings 12 provided with hinged caps having locking springs '0 as shownin Fig. 3. This arrangement allows of the feed roller being quicklyremoved when inspection of the folder becomes necessary. By tighteningup the screw g the front end of the spindle is raised more or less, thatis to say, the milled roller r is pressed more or less toward the feedroller 2;. This is a simple and certain means of regulating thepressure, with or without creasing of the fold forming the longitudinaljoint of the paper tube. By varying the diameter of the feed roller othe feed forward of the paper is modified proportionally, and differentlengths of tubes can be obtained at pleasure.

The action of the machine is such that the various operations abovedescribed are effected in regular order, so that a paper tube ismanufactured at each revolution of the shaft 1).

Having thus described my invention, what I claim is 1. In a machine formaking non-pasted paper tubes, a continuous tube forming mechanismconsisting of a shaper q, a loose shaper u, a cylindrical spindle r,presser 8, folder t attached to spindle r, milled roller 1*, feedroller'12 and automatic cutting device i, F, all said parts being combined andadapted to operate substantially as described and for the purposes setforth.

2. In a machine for making non-pasted tubes an edge creasing andinterlocking mechanism combining therein a spindle r, a loose shaper u,a former t a milled roller r arranged within said spindle, and a creaseror roll 1) located directly above said roller r all said parts beingcombined and adapted to operate, substantially as described and for thepurposes set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
